What is Glendalough?

The Story of Saint Kevin
Around the year 498 AD, Saint Kevin arrived in this secluded valley seeking solitude. Living in a cave above the Upper Lake (St. Kevin's Bed), he meditated among animals, practiced asceticism, and became known for his deep connection to nature and divine wisdom.
Legend: Kevin once held out his arms in prayer so long that a blackbird built a nest in his hand — and he waited until the chicks were hatched before moving.
Soon, a monastic community formed around him. Glendalough became a spiritual and educational powerhouse, surviving Viking raids and influencing Christianity in Ireland for centuries.
Explore the Monastic City
The entrance to Glendalough's Monastic City feels like a portal to the past. Must-see ruins include:
- The Round Tower — Nearly 1,000 years old, used as a bell tower and safehouse during raids.
- St. Kevin's Church ("the Kitchen") — Known for its chimney-shaped roof.
- The Cathedral — The valley's largest stone ruin — peaceful and atmospheric.
- Medieval Gateway — One of Ireland's only surviving monastic stone entrances.
- Celtic Tombs and High Crosses — A hauntingly beautiful cemetery.
Tip: Visit early morning or golden hour for ethereal lighting in your photos.
